To all lw hom t may concern.'

Be it known that I, WALLACE S. WAR- Nocn, citizen of the 4United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Steam-Producers, of which the following is a full, clear, concise, and exact description.

My invention relates to apparatus for producing steam and has for its object the provision of a construction wherebythe steam may be dried, one use of the dry steam being to eect the elimination of static charges of electricity from sheets of paper thatn are passing through printing presses.

In carrying out my invention I employ a water container, means for heating the water in the container to produce steam, a pipe for conveying steam from the container and perforated to permit discharge of steam therefrom, and meansv for effecting the flow of heated gas through the steam preferably after such steam has been discharged' from the pipe. l j

In the preferred embodiment of the invention the container is surrounded by a jacket that is spaced apart therefrom, a pipe leading from the jacket for conveying the gas and surrounding the pipe that conveys the steam. The same heating means, such as a gas burner, which converts the water into steam is also effective in supplying heated gas, such as the products of combustion generated at the burner, to the space between the jacket and the water container and the pipe communicating with this space. Thus a single sourcev of heat serves to generate the steam and to furnish dry hot gas that passes through the steam to absorb the' moisture therefrom in order that the steam may issue from the equipment in such a dry state as readily to effect the elimination of static charges of electricity, although the invention is not to be limited to any particular use to which it may be put.

The invention will be fully rdescribed in connection with the accompanying drawing showing thev preferred embodiment thereof and in which Figure 1 is a longitudinal sectional elevation of a steam generator j equipped in accordance with the invention;

Fig. 2 is a sectional view on line 2 2 of Fig. 1 but on a larger scale; and 3 is a sectional view on line 3-3 of Fig. 1, also on a larger scale. ,Like parts 41'@ indicated by Vsimilar charrounds the container 2 and is spaced apart therefrom, the iioor 4 of the container being rca.

laterally extended to join the jacket andy also constitute a floor beneath the space that-'is between the jacket and the container. Apertures 5 are provided in the portion of the floor 4 that underliesthe space between the jacket and the container. The jacket is continued downwardly, as indicated at 6, and is opened at its lowermost end where it is supported upon the legs 7. Any suitable source of heat may be employed to heat the water, the source of heat 8 which is illustrated bemg below the floor 4 and capable of burning gas supplied thereto through the pipe 9 and an air mixing valve 10 that is provided to establish a suitable mixture of air and gas passing to lthe burner. The lower continuation of the jacket 3 is provided with openings 11. The jacket 3, and particularly its lower extension, is preferably cylindrical and I provide a cylindrical damper 12 in the lower continuation of the jacket that immediately underlies the t ioor 4. This damper has a horizontal portion k13 lng openings 14 adapted to be brought into registry with the 'openings 5 upon suitable rotary adjustment of the damper. The cylindrical portion of the damper has openings 15 adapted to be brought into registry with the openings 11 inthe lower portion ofy the jacket. The sets of vopenings 14 and 15 are offset so that when the openings 14 in the damper are in registry with the openings 5 in the floor 4, the openings 15 are brought out of registry with the openings 11 and, when the openings 15 inthe damper arein registry with the openings 11 in the lower portion of the jacken/thel openings 14 are brought out of registry with the openings 5y in the licor 4. Initially, the damper 12 is so adjusted that the openings 5 and'14v yare closed, the water being brought to a steam generating temperature during this adjustment of the damper.' When the water has been heated to a boiling point the damper is adjusted to bringftheV openings 5 and'14 intok registry so that the lheated air other gas, namely the products of combustion due to the operation of the burner 8, may pass upwardly through the space between the container and the jacket, from which lspace the heated gas is discharged into the pipel through which-the wet steam is Ydischarged into the space that inter-venes between the two nested pipes 16 and 1'?. The steam thus discharged iinds its way through the perorations 19 Jformed in the pipe 16 along the same. The heated gas that is conveyed by the pipe 16 passes through the steam which 1s finding its way from the perforations 18 through the per'torations 19 and across'the path followed by the heated gas.

In order that the gas may be most effec-A` tive in the discharge ot itstunction, I provide a transversely corrugated deflectorQO within the gas pipe and extending from an upper portion of this pipe to a' pla-cebeneath and along the steam pipe where the deiiector is spaced apart from both pipes and serves to direct the upward flow oi' gas into the steam that is flowing from the perforations 18 to the perforations 19.1

j In order that the defiector may more effec-V tively discharge its function which is the even distribution of the gas `throughout the steam, the corrugations in the deflector fare closer together and `shallower at the end of the deiiector-which is nearer the water conlarly described the preferred embodiment` of `my invention I do not wish to be limited to the precise details ot construction shown as changes may readily be made without departing from the spirit of my invention,

but having thus described my invention I claim as new and desire to secure by Let-` ters Patent the ollowingfz j* 1.
